Professor Matt Hitchman's Research Group

We study the dynamics of atmospheric motions from mesoscale to global scale, with a focus on the middle atmosphere and stratosphere - troposphere exchange. We employ chemical transport modeling, analysis of global meteorological fields, analysis of satellite constituent distributions, and aircraft flight data to better understand the general circulation and dynamical transport mechanisms underlying global change.

Ozone STE

Chemical Transport Modeling

We use the UWNMS to study transport pathways, the origin of the ozone croissant, shape of the ozone hole, stratosphere troposphere exchange near midlatitude cyclones and convective complexes, regional air quality modeling, and mercury deposition.

Ozone Croissant

Analysis of Satellite Constituent Data

Climatologies of stratospheric aerosol, water vapor, and ozone are derived from satellite instruments, including LIMS, SAM, SAGE, UARS, POAM, and Aura.

Ozone Croissant

Dynamics and Global Data Analysis

Studies include wave mean flow interaction in the equatorial and extratropical middle atmosphere, inertial instability, the quasibiennial oscillation, ozone transport, and Rossby wave breaking.
